BACKGROUND

A process management framework provides a structure and tool for managing different process flows. The process management framework provides interactions between many different types of applications to support a process flow.

SUMMARY

According to some possible implementations, a device may include one or more memories, and one or more processors, operatively coupled to the one or more memories, to receive a request for an operation that includes a plurality of processing steps and process the request to identify metadata information. The one or more processors may determine a first processing step, of the plurality of processing steps, based on the metadata information and process the metadata information to select a first microservice, of a plurality of microservices, to call and a first transport protocol, of a plurality of transport protocols, to utilize to call the first microservice. The one or more processors may call, utilizing the first transport protocol, the first microservice to cause the first microservice to perform the first processing step, and receive, from the first microservice and based on calling the first microservice, a first output that indicates a result of the first microservice performing the first processing step. The one or more processors may determine, based on the first output and the metadata information, a second processing step of the plurality of processing steps. The one or more processors may process the first output and the metadata information to select a second microservice, of the plurality of microservices, to call and a second transport protocol, of the plurality of transport protocols, to utilize to call the second microservice, wherein the second transport protocol is different from the first transport protocol. The one or more processors may call, utilizing the second transport protocol, the second microservice to cause the second microservice to perform the second processing step, and receive, from the second microservice and based on calling the second microservice, a second output that indicates a result of the second microservice performing the second processing step. The one or more processors may provide a response to the request based on the first output and the second output.

According to some possible implementations, a non-transitory computer-readable medium may store instructions that comprise one or more instructions that, when executed by one or more processors, cause the one or more processors to receive a request for an operation that includes a plurality of processing steps and process the request to identify metadata information. The one or more instructions, when executed by the one or more processors, may cause the one or more processors to determine a first processing step, of the plurality of processing steps, based on the metadata information and process the metadata information to select a first microservice, of a plurality of microservices, to call and a first transport protocol, of a plurality of transport protocols, to utilize to call the first microservice. The one or more instructions, when executed by the one or more processors, may cause the one or more processors to send first information related to the first processing step, the first microservice, and the first transport protocol to one or more servers for storage and call, utilizing the first transport protocol, the first microservice to cause the first microservice to perform the first processing step. The one or more instructions, when executed by the one or more processors, may cause the one or more processors to receive, from the first microservice and based on calling the first microservice, a first output that indicates a result of the first microservice performing the first processing step, and determine, based on the first output and the metadata information, a second processing step of the plurality of processing steps. The one or more instructions, when executed by the one or more processors, may cause the one or more processors to process the first output and the metadata information to select a second microservice, of the plurality of microservices, to call and a second transport protocol, of the plurality of transport protocols, to utilize to call the second microservice, wherein the second transport protocol utilizes a different transmission synchronization from the first transport protocol. The one or more instructions, when executed by the one or more processors, may cause the one or more processors to send second information related to the second processing step, the second microservice, and the second transport protocol to the one or more servers for storage, and call, utilizing the second transport protocol, the second microservice to cause the second microservice to perform the second processing step. The one or more instructions, when executed by the one or more processors, may cause the one or more processors to receive, from the second microservice, and based on calling the second microservice, a second output that indicates a result of the second microservice performing the second processing step, and provide a response to the request based on the first output and the second output.

According to some possible implementations, a method may include receiving, by a server device, a request for an operation that includes a plurality of processing steps, and processing, by the server device, the request to identify metadata information. The method may include determining, by the server device, a first processing step, of the plurality of processing steps, based on the metadata information, and processing, by the server device, the metadata information to select a first microservice, of a plurality of microservices, to call and a first transport protocol, of a plurality of transport protocols, to utilize to call the first microservice. The method may include calling, by the server device and utilizing the first transport protocol, the first microservice to cause the first microservice to perform the first processing step, and receiving, by the server device, from the first microservice, and based on calling the first microservice, a first output that indicates a result of the first microservice performing the first processing step. The method may include determining, by the server device and based on the first output and the metadata information, a second processing step of the plurality of processing steps, and processing, by the server device, the first output and the metadata information to select a second microservice, of the plurality of microservices, to call and a second transport protocol, of the plurality of transport protocols, to utilize to call the second microservice, wherein the second transport protocol is different from the first transport protocol. The method may include calling, by the server device and utilizing the second transport protocol, the second microservice to cause the second microservice to perform the second processing step, and receiving, by the server device, from the second microservice, and based on calling the second microservice, a second output that indicates a result of the second microservice performing the second processing step. The method may include sending, by the server device, information related to the first output and the second output to one or more servers for storage, and providing, by the server device, a response to the request based on the first output and the second output.

DETAILED DESCRIPTION

The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.

A microservices-based architecture may be used for distributed applications that handle process flows. In a microservices-based architecture, a process management framework deploys small, independent services, known as microservices, that communicate using transport protocols. However, current process management frameworks cannot handle using more than one transport protocol for microservices communication. Moreover, current process management frameworks do not provide capabilities to resume or retry a microservice, track the status of a process flow, or analyze the process management framework's performance.

Some implementations described herein provide a cloud-based process management framework that permits microservices to communicate using different transport protocols. In some implementations, the process management framework is capable of communicating with a plurality of microservices where at least one of the plurality of microservices uses a synchronous transport protocol and at least one of the plurality of microservices uses an asynchronous transport protocol. In some implementations, the process management framework provides a resume and/or retry capability for calling microservices. In some implementations, the process management framework stores information related to processing of a processing step, which allows for real-time status tracking of the processing step. In some implementations, the process management framework stores raw data related to the operation of the process management framework.

In this way, the process management framework can handle calls to an expanded universe of microservices and, thereby, provide a more robust microservice-based architecture. Some implementations described herein may reduce or eliminate duplicative job performance by multiple process management frameworks, thereby improving process flow performance. In addition, some implementations described herein may improve speed and efficiency of the process flows and conserve computing resources (e.g., processor resources, memory resources, and/or the like). Further, some implementations described herein may reduce or eliminate overloading of a process management framework, thereby improving functioning of the process management framework.

FIGS. 1A-1G are diagrams of an example implementation 100 described herein. As shown in FIG. 1A, example implementation 100 may include a command engine platform, a metadata server, a persistence server, a status server, an exception server, a client device, and a microservice server. In some implementations, the command engine platform may be associated with a cloud computing environment. In some implementations, the command engine platform may include a command engine and plugins. In some implementations, the command engine may include a status tracker module, an exception handler module, and a key generator module. In some implementations, the plugins may include a metadata information validator, a business outcome resolver, and a step builder. In some implementations, the microservice server may provide access to one or more microservices. In some implementations, the metadata server, the persistence server, the status server, and the exception server are each operatively connected to a data structure.

As shown in FIG. 1B, and by reference number 102, the client device may send a request to the command engine platform. In some implementations, the client device is a communication and/or computing device, such as a mobile phone, a laptop computer, a tablet computer, and/or the like. In some implementations, the client device may include one or more applications and/or processes that, when executed by one or more processors of the user device, facilitate data communications with the command engine platform. In some implementations, the request may be associated with an operation (e.g., a process flow). For example, the client device may send a request to the command engine platform asking the command engine platform to process an applicant's credit card application (referred to herein as “the credit card application scenario”), where an operation may process the credit card application.

In some implementations, the operation is associated with metadata. In some implementations, the metadata may indicate that an operation includes a plurality of processing steps. For example, in the credit card application scenario, the metadata may indicate that an operation to process the credit card application may include a plurality of processing steps, such as, verifying the applicant's identification information, performing a credit check on the applicant, verifying the authenticity of the credit card application, and/or the like.

In some implementations, each processing step, of the plurality of processing steps, is associated with metadata information, which is comprised in the metadata. In some implementations, the metadata information may conform to a human-readable or machine-readable data format, such as JavaScript Object Notation (JSON), Hypertext Markup Language (HTML), YAML Ain't Markup Language (YAML), Extensible Markup Language (XML), and/or the like. For each processing step, the metadata information may indicate a microservice that performs the processing step. For example, in the credit card application scenario, the metadata information, associated with the processing step to verify the applicant's identification information, may indicate that an identification verification microservice performs the processing step to verify the applicant's identification information, and the metadata information associated with the processing step to perform a credit check on the applicant may indicate that a credit check microservice performs the processing step to perform a credit check on the applicant.

In some implementations, the metadata information may include processing step information. The processing step information may indicate a transport protocol to be used to call the microservice that performs the processing step, an item of call information to pass to the microservice that performs the processing step, a retry rate for calling the microservice that performs the processing step, a retry period for calling the microservice that performs the processing step, one or more next processing steps, one or more next microservices that perform the one or more next processing steps, one or more transport protocols to be used to call the one or more next microservices that perform the one or more next processing steps, and/or the like. In some implementations, the transport protocol may be an asynchronous transport protocol. In some implementations, the transport protocol may be a synchronous transport protocol.

As further shown in FIG. 1B, and by reference number 104, the command engine in the command engine platform may receive the request and, based on receiving the request, process the request to determine a name of the operation. In some implementations, the command engine may utilize an event listener to listen for client device requests. The event listener may listen for the request at a transport protocol interface, where the client device sends the request, using a transport protocol, to the transport protocol interface. In some implementations, the event listener may be capable of listening for requests sent by different client devices using different transport protocols. For example, the event listener may be capable of listening for and distinguishing between requests made using a Hypertext Transfer Protocol (HTTP) and an Apache Kafka protocol (Kafka).

In some implementations, the command engine may parse the request to determine the name of the operation. In some implementations, the command engine may utilize a lookup table to determine the name of the operation. In some implementations, the command engine may parse the request using natural language processing to determine the name of operation.

As further shown in FIG. 1B, and by reference number 106, the command engine may send, based on determining the name of the operation, a query using the name of the operation to the metadata server. For example, in the credit card application scenario described herein, the command engine may send the name of the operation (e.g., to process the applicant's credit card application) to the metadata server. In some implementations, the metadata server, based on receiving the name of the operation, may send the metadata information associated with a processing step of the plurality of processing steps to the command engine. For example, the metadata server may send, in the credit card application scenario, the metadata information associated with verifying the applicant's identification information to the command engine.

In some implementations, as further shown be reference number 106, the command engine may process the metadata information to determine the processing step, the microservice that performs the processing step, and a transport protocol to use to call the microservice that performs the processing step. For example, in the credit card application scenario, the command engine may process the metadata information to determine the verifying the applicant's identification information processing step, the identification verification microservice that performs the verifying the applicant's identification information processing step, and the transport protocol for calling the identification verification microservice. In some implementations, the command engine may receive the metadata information from the metadata server, detect the format of the metadata information (e.g., JSON, HTML, YAML, XML, and/or the like), and identify, based on the detected format, the processing step, the microservice that performs the processing step, and the transport protocol. In some implementations, the command engine may call the step builder plugin to process the metadata information to determine the processing step, the microservice to call to perform the processing step, and the transport protocol.

As further shown in FIG. 1B, and by reference number 108, the command engine may call, based on determining the processing step, a key generator module. As shown by reference number 110, the key generator module may generate an identification key identifying the processing step. In some implementations, the key generator module may generate an identification key, which may be used to facilitate real-time tracking of the processing step. As shown by reference number 112, the command engine may send the identification key to a status server for storage. In some implementations, by assigning the identification key to the processing step, the command engine platform that is processing multiple requests at the same time, many of which may be associated with the same and/or similar operations and processing steps, can keep track of any individual processing step by the identification key. In this way, the command engine platform may facilitate tracking or troubleshooting of an operation and/or processing step and thereby conserve processor and/or memory resources that would otherwise be used to track or troubleshoot an operation in an inefficient manner.

In some implementations, the status server may store the identification key in a data structure, such as a database, a table, a linked-list, a tree, and/or the like. In some implementations, the data structure may be provided in a memory associated with the status server. In some implementations, the command engine may send additional information to the status server to store with the identification key, such as information concerning the processing step (e.g., the name of the processing step), information concerning the metadata information (e.g., information identifying the transport protocol), information concerning the command engine platform (e.g., information about computational resources, workload, and/or the like) and/or the like. In some implementations, the status server may store the identification key and the additional information so that the command engine platform, client device, or another device, may query the status server for real-time information about the processing step.

As shown in FIG. 1C, and by reference number 114, the command engine platform may call, based on determining the processing step, a metadata information validator plugin. A plugin is a software component that performs a function, task, or activity. A plugin may include a computer program, an application, a process, a service, a microservice, and/or the like. The command engine platform may comprise a plurality of plugins, where the functionality of the metadata information validator plugin may be performed by one or more of the plurality of plugins. In some implementations, the command engine may call the metadata information validator plugin to verify that the item of call information can be processed by the microservice that performs the processing step.

As shown in FIG. 1C, and by reference number 116, the metadata information validator plugin may validate the metadata information. The metadata information validator plugin may perform validation steps to ensure that the microservice that performs the processing step and the processing step information is complete, correct, and/or formatted correctly. For example, in the credit card application scenario, where the processing step is to verify the applicant's identification information, the metadata information validator plugin may check that the metadata information correctly identifies the identification verification microservice and/or contains the identification information for the identification verification microservice to process.

As shown in FIG. 1C, and by reference number 118, the metadata information validator plugin may send, based on validating the metadata information, validation information regarding the metadata information to the status tracker module in the command engine. In some implementations, the validation information may include information identifying the processing step, the microservice that performs the processing step, the item of call information, and/or an output indicating a result of the validation process (e.g., “validation complete,” “validation complete with warnings,” “validation failed,” and/or the like). In this way, the command engine may avoid calling the microservice that performs the processing step in some situations where the microservice that performs the processing step will not run successfully, thereby reducing an amount of processing associated with calling the microservice that performs the processing step, and thereby conserving processor and/or memory resources of the command engine platform that would otherwise be used to call the microservice.

As shown in FIG. 1C, and by reference number 120, the command engine may send, based on receiving the validation information, the validation information to the status server for storage. In some implementations, the command engine may send a command to the status server to associate the validation information with the identification key when storing the validation information.

As shown in FIG. 1C, and by reference number 122, the command engine may determine, based on receiving the validation information, first information that concerns identifying a state of the processing step. In some implementations, the first information may include information concerning the validation status information. In some implementations, the first information may indicate information identifying the processing step, the microservice that performs the processing step, the transport protocol, the item of call information, the output indicating a result of the validation process (e.g., “validation complete,” “validation complete with warnings,” “validation failed,” and/or the like), and/or the like.

As shown in FIG. 1C, and by reference number 124, the command engine may send, based on determining the first information, the first information to a persistence server for storage. The persistence server may store the first information in a data structure, such as a database, a table, a linked-list, a tree, and/or the like. In some implementations, the data structure may be provided in a memory associated with the persistence server. In some implementations, the persistence server may store the first information so that the command engine platform, the client device, or another device may run computational analytics on the performance of the command engine platform. In this way, the command engine platform's processor and memory resources may be more efficiently utilized to continue handling operations and/or processing steps.

As shown in FIG. 1D, and by reference number 126, the command engine may call, based on validating the metadata information, the microservice that performs the processing step using the transport protocol. In some implementations, the command engine may also send the item of call information to the microservice that performs the processing step. For example, in the credit card application scenario, the command engine may call the identification verification microservice that performs the processing step to verify the applicant's identification information and may send identification call information (e.g., name of the applicant, applicant's address, applicant's Social Security number, and/or the like) to the identification verification microservice. In some implementations, the transport protocol may be asynchronous, such as Kafka, RabbitMQ, and/or the like. In some implementations, the transport protocol may be synchronous, such as HTTP.

As shown in FIG. 1D, and by reference number 128, the microservice that performs the processing step may run, based on being called by the microservice that performs the processing step, and generate a microservice output. In some implementations, the microservice that performs the processing step may process the item of call information to generate a microservice output. For example, in the credit card application scenario, the identification verification microservice that performs the processing step to verify the applicant's identification information may process the identification call information (e.g., name of the applicant, applicant's address, applicant's Social Security number, and/or the like) by comparing the identification call information and other information associated with the applicant that is available to the identification verification microservice. In some implementations, the microservice that performs the processing step may generate a microservice output that indicates whether the microservice that performs the processing step ran successfully or unsuccessfully. In some implementations, the microservice output may be in a computer readable and/or human readable format.

As shown in FIG. 1D, and by reference number 130, the microservice that performs the processing step sends, based on generating the microservice output, the microservice output to the command engine platform. In some implementations, the microservice server may communicate the microservice output to the command engine platform via the transport protocol. In some implementations, the transport protocol may be asynchronous, such as Kafka, RabbitMQ, and/or the like. In some implementations, the transport protocol may be synchronous, such as HTTP.

As shown in FIG. 1E, and by reference number 132, the command engine may send, based on receiving the microservice output, the microservice output to a business outcome resolver plugin. In some implementations, the functionality of the business outcome resolver plugin may be performed by one or more plugins. In some implementations, the command engine may call the business outcome resolver plugin to determine whether the microservice output is acceptable for further processing of the operation.

As shown in FIG. 1E, and by reference number 134, the business outcome resolver plugin processes the microservice output and generates a business outcome. In some implementations, the business outcome resolver may process the microservice output and generate a business outcome that indicates whether the call to the microservice that performs the processing step was successful. In some implementations, the business outcome resolver may process the microservice output using a set of rules to generate the business outcome. The set of rules may be specific to the processing step and/or the microservice that performs the processing step. For example, in the credit card application scenario, the identification verification microservice (that performs the processing step to verify the applicant's identification information) may produce a microservice output indicating that identification of the applicant failed. The business outcome resolver may then use a set of rules to generate a business outcome that indicates why the identification verification microservice failed or alternative processing steps and microservices to call to continue processing the credit card application (e.g., a processing step to get new applicant identification information using a fetch applicant identification information microservice).

In some implementations, the business outcome resolver may process the microservice output using the set of rules and determine that an exception occurred while running the microservice that performs the processing step. In some implementations, an exception may indicate that the microservice that performs the processing step failed to finish, the microservice output is corrupt and/or nonmeaningful, the microservice output indicates a runtime error, and/or the like. In some implementations, an exception may indicate that the microservice that performs the processing step may need to be run again. In some implementations, the business outcome resolver may generate the business outcome to indicate an exception. In some implementations, the business outcome may be in a natural language format that is readable and/or meaningful to a human (e.g., the business outcome may state “processing step successful,” “microservice timed out,” “rerun processing step,” “microservice exception,” and/or the like).

As shown in FIG. 1E, and by reference number 136, the business outcome resolver plugin, based on generating the business outcome, may send the business outcome to the status tracker module in the command engine. As shown in FIG. 1E, and by reference number 138, the command engine may send, based on receiving the business outcome, the business outcome to the status server for storage. In some implementations, the command engine may send a command to the status server to associate the business outcome with the identification key when storing the validation information.

As shown in FIG. 1E, and by reference number 140, the command engine may determine, based on receiving the business outcome, second information that concerns identifying a state of the processing step. In some implementations, the second information may include information concerning the business outcome. In some implementations, the second information may indicate information identifying the processing step, the microservice that performs the processing step, the item of call information, the business outcome, and/or the like.

As shown in FIG. 1E, and by reference number 142, the command engine may send, based on determining the second information, the second information to a persistence server for storage. In some implementations, the persistence server may store the second information so that the command engine platform, the client device, or another device may run computational analytics on the performance of the command engine platform.

As shown in FIG. 1F, and by reference number 144, the command engine platform, based on receiving the business outcome, may call the step builder plugin. The functionality of the step builder plugin may be performed by one or more plugins. In some implementations, the command engine may call the step builder plugin to determine a next processing step identifier.

As shown in FIG. 1F, and by reference number 146, the step builder plugin may send a query to the metadata server. In some implementations, the step builder plugin may process the business outcome to generate the query to send to the metadata server. In some implementations, the step builder plugin processes the business outcome in view of the one or more next processing steps (in the processing step information of the metadata information) to determine the query. For example, in the credit card application scenario, in the case where the business outcome indicates that the identification verification microservice (that performs the processing step to verify the applicant's identification information) ran successfully, the step builder plugin may determine the query based on the one or more next processing steps that indicates the next processing step is a credit check processing step. In the case where that the identification verification microservice ran unsuccessfully, the step builder plugin may determine the query based on the one or more next processing steps that indicates, based on an unsuccessful business outcome, the next processing step is a processing step to get new applicant identification information.

As further shown by reference number 146, the metadata server, based on receiving the query, may send additional metadata information to the step builder plugin. In some implementations, the additional metadata information may conform to a human-readable or machine-readable data format, such as JSON, HTML, YAML, XML, and/or the like. The additional metadata information may indicate a next processing step and next processing step information. The next processing step may indicate a next microservice that performs the next processing step and the next processing step information may indicate a next transport protocol to call the next microservice, a next item of call information to pass to the next microservice that performs the next processing step, and/or the like.

As shown in FIG. 1F, and by reference number 148, the step builder plugin may determine the next processing step identifier based on the additional metadata information. In some implementations, the step builder plugin may receive the additional metadata information from the metadata server, detect the format of the additional metadata information (e.g., JSON, HTML, YAML, XML, and/or the like), and identify, based on the detected format, the next processing step, the next microservice that performs the next processing step, and the next transport protocol, and/or the like. In some implementations, the next transport protocol is different than the transport protocol. In some implementations, the next transport protocol utilizes a different transmission synchronization from the transport protocol.

As shown in FIG. 1F, and by reference number 150, the step builder plugin, based on determining the next processing step identifier, may send the next processing step identifier to the status tracker module in the command engine. As shown in FIG. 1F, and by reference number 152, the command engine, based on receiving the next processing step identifier, may send the next processing step identifier to the status server for storage. In some implementations, the command engine may send a command to the status server to associate the next processing step identifier with the identification key when storing the next processing step identifier.

As shown in FIG. 1F, and by reference number 154, the command engine may determine the next processing step based on the next processing step identifier. In some implementations, the command engine may determine the next processing step in a similar manner to that described elsewhere herein (see, e.g., the description accompanying FIG. 1A). In some implementations, the command engine facilitates performance of the next processing step in a similar manner to that described elsewhere herein (see, e.g., the description accompanying FIGS. 1A-1F).

In some implementations, the command engine platform may send a response to the request to the client device, where the response is based on output from the microservice that performs the processing step and output from the next microservice that performs the next processing step. For example, in the credit card application scenario, the command platform may run the identification verification microservice that performs the processing step to verify the applicant's identification information and the credit check microservice that performs the processing step to perform a credit check on the applicant, where output from each microservice indicates success. The command platform may then may send a response to the client device that indicates the operation to process an applicant's credit application was successful.

In some implementations, the next processing step is associated with a next microservice (that performs the next processing step) that is different from the microservice (that performs the processing step). In some implementations, the next processing step is associated with a next transport protocol that is different from the transport protocol (that is associated with the processing step). In some implementations, the next processing step is associated with a next transport protocol that utilizes a different transmission synchronization from the transport protocol (that is associated with the processing step).

In the case where the business outcome indicates an exception, the command engine platform provides additional functionality. As shown in FIG. 1G, and by reference number 156, the business outcome resolver may process the microservice output and determine that an exception occurred while running the microservice that performs the processing step. The business outcome resolver may then send the business outcome that indicates an exception to the exception handler module in the command engine.

As shown in FIG. 1G, and by reference number 158, the exception handler module, based on receiving the business outcome that indicates an exception, may process the business outcome and determine a retry time for calling the microservice that performs the processing step and a retry quantity for calling the microservice that performs the processing step. In some implementations, the exception handler module may determine the retry time and the retry quantity based on the command engine's current or future work load. For example, the exception handler may analyze the command engine's workload queue, which may contain information concerning operations and/or processing steps that the command engine is currently handling or scheduled to handle, and determine a retry time for a time when the command engine has optimal availability.

In some implementations, the exception handler module may determine the retry time and the retry quantity based on the metadata information. In some implementations, the exception handler module may determine the retry time based on the metadata information's processing step information, which may indicate the retry rate for calling the microservice that performs the processing step and/or the retry period for calling the microservice that performs the processing step. In some implementations, the exception handler module may determine the retry quantity based on the metadata information's processing step information, which may indicate the retry rate for calling the microservice that performs the processing step and/or the retry period for calling the microservice that performs the processing step. In some implementations, the exception handler module may create a schedule, based on the retry time and retry quantity, for calling the microservice that performs the processing step.

In some implementations, the exception handler may determine a retry rate related to the microservice that performs the processing step and a retry period related to the microservice that performs the processing step in a similar manner to that described for determining the retry time and the retry quantity. In some implementations, the exception handler module may create a schedule, based on the retry rate related to the microservice that performs the processing step and the retry period related to the microservice that performs the processing step, to call the microservice that performs the processing step.

As shown in FIG. 1G, and by reference number 160, the command engine platform may communicate with the exception server to facilitate determining the retry rate and the retry quantity, and calling the microservice that performs the processing step. The command engine may send the ID key, metadata information, retry time, retry quantity, and/or the like to the exception server for storage. The exception server may store the ID key, metadata information, retry time, retry quantity, and/or the like in a data structure, such as a database, a table, a linked-list, a tree, and/or the like. In some implementations, the data structure may be provided in a memory associated with the exception server. In some implementations, the exception handler module and exception server may communicate to update the retry time and retry quantity. For example, the exception handler may decrease the retry quantity each time the microservice that performs the processing step is called and runs unsuccessfully. If the retry quantity decreases to zero, the microservice that performs the processing step may not be scheduled to be called again.

As shown in FIG. 1G, and by reference number 162, the command engine platform calls the microservice that performs the processing step using the transport schedule at the retry time. In some implementations, the command engine may call the microservice in accordance with the schedule. In some implementations, the command engine may call the microservice at the retry time.

As indicated above, FIGS. 1A-1G are provided merely as examples. Other examples are possible and may differ from what was described with regard to FIGS. 1A-1G.

As such, command engine platform 230 may be easily and/or quickly reconfigured for different uses.

In some implementations, as shown, command engine platform 230 may be hosted in cloud computing environment 232. Notably, while implementations described herein describe command engine platform 230 as being hosted in cloud computing environment 232, in some implementations, command engine platform 230 may not be cloud-based (i.e., may be implemented outside of a cloud computing environment) or may be partially cloud-based.

Cloud computing environment 232 includes an environment that hosts command engine platform 230. Cloud computing environment 232 may provide computation, software, data access, storage, and/or other services that do not require end-user knowledge of a physical location and configuration of a system and/or a device that hosts command engine platform 230. As shown, cloud computing environment 232 may include a group of computing resources 234 (referred to collectively as “computing resources 234” and individually as “computing resource 234”).

Computing resource 234 includes one or more personal computers, workstation computers, server devices, or another type of computation and/or communication device. In some implementations, computing resource 234 may host command engine platform 230. The cloud resources may include compute instances executing in computing resource 234, storage devices provided in computing resource 234, data transfer devices provided by computing resource 234, etc. In some implementations, computing resource 234 may communicate with other computing resources 234 via wired connections, wireless connections, or a combination of wired and wireless connections.

Virtual machine 234-2 may be either a system virtual machine or a process virtual machine, depending upon use and degree of correspondence to any real machine by virtual machine 234-2. A system virtual machine may provide a complete system platform that supports execution of a complete operating system (“OS”). A process virtual machine may execute a single program and may support a single process. In some implementations, virtual machine 234-2 may execute on behalf of a user (e.g., a user of client device 210), and may manage infrastructure of cloud computing environment 232, such as data management, synchronization, or long-duration data transfers.

Virtualized storage 234-3 includes one or more storage systems and/or one or more devices that use virtualization techniques within the storage systems or devices of computing resource 234. In some implementations, within the context of a storage system, types of virtualizations may include block virtualization and file virtualization. Block virtualization may refer to abstraction (or separation) of logical storage from physical storage so that the storage system may be accessed without regard to physical storage or heterogeneous structure. The separation may permit administrators of the storage system flexibility in how the administrators manage storage for end users. File virtualization may eliminate dependencies between data accessed at a file level and a location where files are physically stored. This may enable optimization of storage use, server consolidation, and/or performance of non-disruptive file migrations.

Hypervisor 234-4 provides hardware virtualization techniques that allow multiple operating systems (e.g., “guest operating systems”) to execute concurrently on a host computer, such as computing resource 234. Hypervisor 234-4 may present a virtual operating platform to the guest operating systems and may manage the execution of the guest operating systems. Multiple instances of a variety of operating systems may share virtualized hardware resources.
